What happened to Janine Vaughan?

Janine Vaughan was last seen in December 2001.

NSW's top homicide cop has a grim message for those who have found themselves in suspicion's spotlight since Janine Vaughan disappeared from a Bathurst street early one morning in December 2001 - nobody has been ruled out.

On Friday, Homicide Squad Commander, Detective Superintendent Scott Cook announced a $1 million reward for information about the suspected murder of the 31-year-old.

Janine’s distraught family - sister Kylie Spelde, brother Adam and father Ian - looked on as Cook said investigators would be applying “new DNA technology” to samples removed from a red car seized a decade ago.

The car is thought to have been driven by Janine’s abductor, but Cook would not speculate.

“We think a local was involved, a Bathurst local in 2001, and we think there are people in Bathurst who have been holding secrets for a long time,” he said.
